A switch driving circuit includes a buffer module, a capacitor module, a first switch module, a second switch module, and a control module. The buffer module generates a driving voltage according to a control voltage. The first switch module is turned on when the control voltage is at a low voltage level to provide a supply voltage to the buffer module and charge the capacitor module by the supply voltage to generate a compensation voltage. The second switch module is turned on when the control voltage is at a high voltage level to provide the compensation voltage to the buffer module. When the supply voltage is higher than a reference voltage, the control module turns on the first switch module and turns off the second module to provide the supply voltage to the buffer module.
